The first performers have been announced for this year's Grammy Awards show, and the list is a doozy: The Black Keys, fun., Mumford & Sons, Rihanna and Taylor Swift. The chance to see all those stars is enough of a reason to stick around for the 3½-hour show.

Just to recap what these artists have racked up this year: Mumford & Sons and fun. are nominated for six Grammys each, while the Black Keys are up for five, and both Rihanna and Swift are nominated for three awards.

What if fun. does a duet with Swift, or Rihanna takes the stage with Mumford & Sons, or the Black Keys teamed up with all of them? That could be like Christmas in February.
